Just in case you might be interested in knowing this. As I remember, the AF mechanism inside this F*300/4.5 is a one big plastic ring (white colour if it matters) with gears (connected to a smaller metal one). Personally, I would be careful and not stress it too much (say, turn the focus ring while the body in AF mode). Also, the IC on the lens mount is very fragile so one must be extremely careful if trying to open the lens. That's my observation when I stripped down one many years ago. I used to be pretty picky on my gears too, but I reckon I am not buying the most expensive equipment on earth, so I just learn to accept what I can afford. I am still learning... :( regards, Alan Chan _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp. - This message is from the Pentax-Discuss Mail List.
